2 ways to measure

Measure the finger, or a ring that already fits her. Both give the same size.

Measure the finger

Cut a thin strip of paper, about 1 cm wide.
Wrap it snugly around the base of the finger.
Mark where the paper overlaps.
Lay it flat and measure the length in millimeters: that number is the size.

Our printable ring sizer has a ready-made strip: cut, wrap, read.

Measure a ring that fits her

Take a ring she already wears on the right finger.
Measure the inside, edge to edge, in millimeters.
Find that number in the inner Ø column of the chart.
Or place the ring on the circles of the printable sizer.

Is it a gift? Borrow one of her rings for 10 minutes: she'll never know.

Print at actual size (100%), then use the strip or the circles. A control line tells you if the print is accurate.

Our sizes are French sizes: the inner circumference of the ring in millimeters. Find hers, then read it in your country's system.

Good to know

6 tips for the right size

When is the best time to measure?

At the end of the day, with warm hands: fingers are a little thinner in the morning and in the cold. Measure 2 or 3 times to be sure.

How do I find her size without asking?

Borrow a ring she wears on the right finger for a few minutes. Measure its inner diameter edge to edge, or place it on the circles of the printable sizer. No ruler at hand? Trace the inside of the ring on a sheet of paper and measure the circle later.

Between two sizes, which one?

The larger one. A wide band feels tighter than a thin one: for a ring wider than 6 mm, go half a size up.

What about the knuckle?

The ring should slide over the knuckle without forcing and not spin once in place. If the knuckle is much wider than the base of the finger, measure both and choose a size in between.

Are all fingers the same size?

No. Measure the exact finger: the ring finger isn't the index, and the dominant hand is often half a size bigger.

What do the sizes mean?

Our sizes are French: the inner circumference of the ring in millimeters. Size 52 = 52 mm around. The chart converts them to US, UK, Italian and Japanese sizes, approximately.
